Petopia is theoretically updated for Patch 5.0.4 now, although I am already aware of a whole bunch of fiddling little issues I need to fix. Still, it should cover the basics. At least long enough for me to log in and tame a fen strider …

Sadly, Warcraft Mounts is not updated yet. That’s next on my list.
And may I say again that I owe a huge debt to the entire Petopia community for gathering and organizing so much data! And especially to Wain for making sure I actually did something with all that data, even if he had to do it for me. <grin>
